5speedz34 Posted November 19, 2008 Report Share Posted November 19, 2008 It's only on the 5speeds in W-body's. It injects oxygen into the exhaust to help burn unburned gases. Quote Link to comment Share on other sites More sharing options...

BXX Posted November 19, 2008 Report Share Posted November 19, 2008 Im a jimmy rig way of helping emissions in other words Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted November 19, 2008 Report Share Posted November 19, 2008 How so? It's no more jimmy rigged than an EGR. Quote Link to comment Share on other sites More sharing options...
BXX Posted November 19, 2008 Report Share Posted November 19, 2008 How so? It's no more jimmy rigged than an EGR. EGRs suck too.. hence there are engines without EGRs anymore as technology has progressed and an EGR works a different way Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted November 19, 2008 Report Share Posted November 19, 2008 I agree emissions suck, but I wouldn't say that it's jerry rigged. EGR's also help to burn unburned gases. Quote Link to comment Share on other sites More sharing options...

Yeah, but redirecting it to the intake to be reburned smog... pfft.. lets dump tons of air into the exhaust and hope it helps much for emissions Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted November 19, 2008 Report Share Posted November 19, 2008 It's shitty but thats the way emissions is. I'm sure if they could think of a better way then they would have. You know the AIR system helps to reburn exhaust gases, not just dilute them? Quote Link to comment Share on other sites More sharing options...

ismellrealbad Posted November 19, 2008 Report Share Posted November 19, 2008 hence there are engines without EGRs anymore as technology has progressed like setting the exhaust cam lobes to close the ex valve early and leave some exhaust still in the cylinder. Chrysler 3.8 V6 is notrious for going back and forth between this and EGR. EGR also REDUCES combustion temps therby lowering NOx emissions.

Addicted To Boost Posted November 20, 2008 Report Share Posted November 20, 2008 A.I.R. Pump? Can't tell from the pic, but I'd assume that's what it is. It came on 5-speed models only. omg dude are you serious? He prolly is used to the 2.8/3.1L that do actually have an air pump, but even at that, they look nothing like that just didnt realize the LQ1 has an electic air pump What are you asking, Chris? Yes, I have only seen the AIR pump system on a 2.8, I've never seen one on a 3.4, but knew they existed. Quote Link to comment Share on other sites More sharing options...
Series8217 Posted November 21, 2008 Report Share Posted November 21, 2008 The air pump injects fresh air into the exhuast to heat up the catalytic converter faster. It serves no other purpose than cat warmup. That's why it only runs at startup. Quote Link to comment Share on other sites More sharing options...

Not true, my brother's 2000 grand prix with the 3800 and an automatic has an AIR pump. It is located behind the front bumper wrap on the drivers side. They are found on CA emission cars and are common to CA and the north east states. I've been finding about 50% of the 97+ Grand Prixs in the jy with the 3800 have the A.I.R. pump and othe other 50% don't. Quote Link to comment Share on other sites More sharing options...
